IMPROVEMENT IN RINGS FOR SPINNING-MACHINES.

Specification forming part of Letters Patent No. 203,573, dated May 14,1878 application filed April 15,

To all whom it may concern:

Be it known that I, NICHOLAS I. ALLEN, of Milford, county of Worcester,State of Massachusetts, have invented an Improvement in Rings forSpinning-Machines, of which the following is a specification:

This invention relates to improvements in rings for spinning-frames, andhas special reference to that class of rings which are made double.

The object of the invention is to produce a very light cheap ring; andthe invention consists in a double ring having a traveler-race common toboth ends of the ring.

Figure 1 represents, in section, one of my improved rings placed inposition on the usual traversing ring-rail; and Fig. 2, a top view ofsuch ring and holder.

My improved ring has an annular race, a, located substantially at thecenter of the ring, and above and below such race are narrow ledges b c,which act to support the traveler d when not held up by the yarn. Thespace between the outer edge of the race and the top for the yarn totravel in without abrasion against the ring.

When the ring, placed as shown in Fig. 1, has been used sufiicientlylong for that portion of the race against which the ends of the travelermove to become worn, the ring will be inverted, and the traveler willthereafter be guided by the unworn side of the race thenplaced nearestthe ring-rail e.

The ring shown may be contained in a holder, f, made adjustable in anyusual way with reference to the spindle-opening.

I claim- As an improved article of manufacture, a double ring with a,single race common to both ends of the ring, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

NICHOLAS I. ALLEN.
